[Resolved]  Siemens Home India — not returning the money that was credited to them by double credit card swipe

Address:

Bangalore, Karnataka, 560035

On november 21, 2017 i called siemens service for servicing my washing machine and got connected to reliable services, who do washing machine service although they are not authorized service partners of siemens. Thinking that they are authorized, i let them service the machine for which they charged some 8000 rupees. The technician swiped my credit card twice by mistake, thereby making me pay twice the actual amount. When i found this out some days later, i called them, and send them the swipe acknowledgement sms for the two transactions.
They said they would refund the amount in 7 days. For the past one month, i and my wife called them many times and were told that it will be done the next day, which never happened.
I am not sure why they show this injustice to me even though i did their payment right after the service was done.

I hope someone would take notice, and resolve this as early as possible.
